Radon Testing in Northwood

Radon Testing in Northwood, Worth County, by Closer Look Inspectors. Northwood is a border county seat just south of the Minnesota line.

Radon testing places an EPA-protocol continuous monitor on a home's lowest livable level to measure radon gas — and it matters across Iowa, where Iowa HHS reports 71.6 percent of homes above the action level — the largest percentage of any state.

Local housing

Homes in Northwood.

Northwood housing runs to small border-city housing, across the town core, on flat till just south of the Minnesota line — and that mix shapes what a radon testing here needs to find.

Local conditions in Northwood

No Iowa law requires a home inspection before a sale — the one mandatory time-of-transfer inspection covers private septic systems (Iowa Code 455B.172) — which makes an independent inspection the only thorough, buyer-side read on a Northwood home. Northwood sits in Worth County, and every Iowa county is EPA Radon Zone 1. Iowa HHS reports Iowa has the largest percentage of homes above the 4.0 pCi/L action level of any state — 71.6 percent in the Iowa Radon Survey — and the Iowa seller disclosure form asks for any known radon test results. Finished basements concentrate it, and only a 48-hour test gives you this home's number. Iowa leaves frost depth to the local building code rather than one statewide number, and the annual freeze-thaw cycle drives the settlement cracks and ice-dam wear that Northwood-area homes face.
